Description

I was really, really hoping to avoid having to include this in the API, but it appears that there are some WebView interfaces (specifically <video> and <audio> HTML tags) which cannot be made to work with cdvfile:// URLs.

(See CB-6079 for the issue which triggered this revelation)

I'm going to create a method (toNativeURL) on Entry objects, inherited by DirectoryEntry and FileEntry, which exposes a URL that can be used as a src attribute for an HTML5 media player.

Usage:

requestFileSystem(PERSISTENT, 0, function(fs) {
    fs.root.getFile("movie.mp4", {}, function(entry) {
        alert(entry.toNativeURL());
        document.getElementById('my-video-player').src=entry.toNativeURL();
    });
});

Developers will be able to use this in all cases where they need to set the src of an HTML audio/video tag, or in any other cases where the WebView doesn't correctly proxy URL requests through the app.
